这是Part1的后续问题。

第2部分:

books_ctrl.js.coffee

myApp.controller "BooksCtrl", ($scope, Book) ->
  $scope.save = () ->
    if $scope.book.id?
      Book.update($scope.book)
    else
      Book.save($scope.book)
    $scope.book = {}
    $scope.getBooks()

book.js.coffee

myApp.factory "Book", ($resource) ->
  $resource("/books/:id", {id: "@id"}, {update: {method: "PUT"}})

   (23.0ms)  commit transaction
Completed 200 OK in 29ms (Views: 1.0ms | ActiveRecord: 24.0ms)

这是我的问题:AngularJS似乎同时执行所有请求。这样GET - 请求在POST - 请求之前执行,这在我的情况下是不良影响。

如何在GET完成后告诉Angular执行POST

1 个答案:

答案 0 :(得分:0)

你可以这样做:

Book.save($scope.book, $scope.getBooks)

或者:

Book.save($scope.book).$promise.then($scope.getBooks)
